# the number of queries. The database still needs to send all the data to Active Record and it still needs to be processed. So it's no
# catch-all for performance problems, but it's a great way to cut down on the number of queries in a situation as the one described above.
#
# Since the eager loading pulls from multiple tables, you'll have to disambiguate any column references in both conditions and orders. So
# <tt>:order => "posts.id DESC"</tt> will work while <tt>:order => "id DESC"</tt> will not. Because eager loading generates the +SELECT+ statement too, the
# <tt>:select</tt> option is ignored.
# Since only one table is loaded at a time, conditions or orders cannot reference tables other than the main one. If this is the case
# Active Record falls back to the previously used LEFT OUTER JOIN based strategy. For example
#
# Post.find(:all, :include => [ :author, :comments ], :conditions => ['comments.approved = ?', true])
#
# You can use eager loading on multiple associations from the same table, but you cannot use those associations in orders and conditions
# as there is currently not any way to disambiguate them. Eager loading will not pull additional attributes on join tables, so "rich
# associations" with +has_and_belongs_to_many+ are not a good fit for eager loading.
# will result in a single SQL query with joins along the lines of: <tt>LEFT OUTER JOIN comments ON comments.post_id = posts.id</tt> and
# <tt>LEFT OUTER JOIN authors ON authors.id = posts.author_id</tt>. Note that using conditions like this can have unintended consequences.
# In the above example posts with no approved comments are not returned at all, because the conditions apply to the SQL statement as a whole
# and not just to the association. You must disambiguate column references for this fallback to happen, for example
# <tt>:order => "author.name DESC"</tt> will work but <tt>:order => "name DESC"</tt> will not.
#
# If you do want eagerload only some members of an association it is usually more natural to <tt>:include</tt> an association
# which has conditions defined on it:
#
# class Post < ActiveRecord::Base
# has_many :approved_comments, :class_name => 'Comment', :conditions => ['approved = ?', true]
# end
#
# Post.find(:all, :include => :approved_comments)
#
# will load posts and eager load the +approved_comments+ association, which contains only those comments that have been approved.
#
# When eager loaded, conditions are interpolated in the context of the model class, not the model instance. Conditions are lazily interpolated
# before the actual model exists.

# will raise ActiveRecord::EagerLoadPolymorphicError. The reason is that the parent model's type
# is a column value so its corresponding table name cannot be put in the +FROM+/+JOIN+ clauses of that early query.
#
# In versions greater than 2.0.2 eager loading in polymorphic associations is supported
# thanks to a change in the overall preloading strategy.
#
# It does work the other way around though: if the <tt>User</tt> model is <tt>addressable</tt> you can eager load
# their addresses with <tt>:include</tt> just fine, every piece needed to construct the query is known beforehand.
# will execute one query to load the addresses and load the addressables with one query per addressable type.
# For example if all the addressables are either of class Person or Company then a total of 3 queries will be executed. The list of
# addressable types to load is determined on the back of the addresses loaded. This is not supported if Active Record has to fallback
# to the previous implementation of eager loading and will raise ActiveRecord::EagerLoadPolymorphicError. The reason is that the parent
# model's type is a column value so its corresponding table name cannot be put in the +FROM+/+JOIN+ clauses of that query.

# ActiveRecord uses table aliasing in the case that a table is referenced multiple times in a join. If a table is referenced only once,
# Active Record uses table aliasing in the case that a table is referenced multiple times in a join. If a table is referenced only once,
# the standard table name is used. The second time, the table is aliased as <tt>#{reflection_name}_#{parent_table_name}</tt>. Indexes are appended
# for any more successive uses of the table name.
